I have played with ML speakers for decades and a few things to keep in mind are: 1) They are line sources that radiate in both directions and 2) they are a capacitive load not a resistive load.
When I looked up the OP's speakers, they are conventional box speakers with dynamic drivers (magnets, coils and cones) plus an unconventional tweeter! A far cry from the MLs of old ...
